Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description:

As depicted in figs. 1 and 2, a kind of driving switch of Double layer rotating track configuration, including shell 7, shell are arranged with outside 7 upper end Knob 8 is arranged with pedestal 4 in lower end, is equipped with rotation axis 1 inside center axis, 1 upper end of rotation axis is connect with knob 8, lower end Equipped with the torsional spring 3 coaxial with rotation axis 1, ejector pin and tooth form 6 are successively arranged with outside torsional spring 3, the tooth form 6 includes upper layer track 60 and lower layer track 61, two layers of track is coaxial, and respectively gear point is evenly distributed on the same circumference, the two track it is identical but Track site of performing is staggered；The ejector pin include relatively rotate 1 coaxial-symmetrical of axis setting upper ejector pin 5 and lower ejector pin 2, it is described on 2 gear points of ejector pin 5 and lower ejector pin 2 relative direction that apical grafting is staggered in upper layer track 60 and lower layer track 61 respectively, and locate In on a straight line line of motion, so that two ejector pin compression movement directions are consistent；The pedestal 4 includes base shell 41, outside pedestal Contact chip 42 and circuit board 43 are equipped in shell 41, the contact chip 42 is arranged in 6 bottom of tooth form, and with the gear of tooth form 6 point one One is corresponding, and the circuit board 43 is arranged in 42 bottom of contact chip and connect with contact chip 42.

The upper layer track 60 and lower layer track 61 are odd gear, specifically, the upper layer track 61 and lower layer track Mark 61 is that the integral structure of the coaxial arrangement in upper and lower level is arranged, and two layers of track is positive the side n shape structure, and wherein n is Odd number greater than 3.

The upper ejector pin 5 and lower ejector pin 2 are lip pencil structure, be symmetricly set on upper layer track 60, lower layer track 61 it is upper On subsurface, the two tail end is connect with torsional spring, and apical grafting is distinguished in the corresponding gear point in upper layer track 60 and lower layer track 61 in tip Place.

In use, turning knob 8, drives rotation axis 1 to rotate the torsional spring 3 of its lower end, and then compress ejector pin and along tooth The track slippage of shape 6 rotates, when the rotation of upper ejector pin 5 is in any shelves site location of upper layer track 60, at 2 rotation of ejector pin at present It in the relative position of the same straight path in lower layer track 61, realizes in the bidirectional balanced force of the direction of motion, improves the torsion of rotation axis 1 Turn process stability, the operating comfort when knob 8 of guarantee reverses；When upper ejector pin 5 and lower ejector pin 2 turn to corresponding gear point Afterwards, corresponding 42 contact of contact chip is connected, and circuit board is powered, and makes the driving switch control to corresponding gear.

In order to reduce the noise that the friction of same material contact slide generates, the tooth form 6 and ejector pin use different materials Be made, the tooth form 6 and ejector pin are made of different materials, and the material of the two be the polyamide being used in conjunction with each other and Polyformaldehyde, i.e. tooth form 6 are made of polyamide material, and corresponding ejector pin is then made of polyformaldehyde；Or tooth form 6 uses poly- first Aldehyde is then corresponded to ejector pin using being made of polyamide, is used using different material matings, be can reduce the two contact friction and is generated Noise, improve operating comfort.
